UndefVarError: closewrite not defined

[KajWiik]

I installed Pages#main (with HTTP v1.10.1) in a clean (activate --temp) environment. The basic example in README.md gives an error:

julia> ┌ Error: error handling request
│   exception =
│    UndefVarError: `closewrite` not defined
│    Stacktrace:
│     [1] (::HTTP.Servers.var"#13#14"{Pages.var"#12#15", HTTP.ConnectionPool.Transaction{Sockets.TCPSocket}, HTTP.Streams.Stream{HTTP.Messages.Request, HTTP.ConnectionPool.Transaction{Sockets.TCPSocket}}})()
│       @ HTTP.Servers ~/.julia/packages/HTTP/IAI92/src/Servers.jl:371
└ @ HTTP.Servers ~/.julia/packages/HTTP/IAI92/src/Servers.jl:373

Also

@async Pages.start();

does not return anything (like Listening on 0.0.0.0:8000...).
Any suggestions?
